I’ve just published release 3.19.0 of IBC to GitHub. Download the zip for your platform from here:

?

?

The main improvement in this release is the resolution of these issues:

?

#142 Login failed - Server disconnected, please try again

#251 Unknown Username.Password/Duplicate Session?

#253 IBC unable to restart after 2.5 days of running. Happened multiple times.

?

Other enhancements:

?

• there is a revised Task Scheduler template for Windows, to ensure that IBC is automatically restarted if it is closed for any reason
• a Cold Restart mechanism has been introduced. This provides an easy way to ensure compliance with IBKR's requirement that TWS/Gateway be fully logged off at some point on Sundays. See the notes for the new ColdRestartTime setting in config.ini
• the User Guide has been updated to include information about IBC's command server
• sample scripts have been provided to enable easy use of IBC's command server

?

The recommended procedure for installing this release is:

?

1. Rename your existing IBC folder, for example to IBC-old, so you can easily revert to it if need be.
2. Create a new IBC folder.
3. Extract the contents of the zip file as described in the User Guide.
4. Update the config.ini and scripts as required. Note that the top-level start scripts have not changed, so you can copy those back from the renamed IBC folder to the new IBC folder rather than update the new copies. These are:

StartTWS.bat

StartGateway.bat

twsstart.sh

gatewaystart.sh

twsstartmacos.sh

gatewaystartmacos.sh

Hi Richard,

?

I am upgrading in phases. I have changed the paper gateway’s configuration file. Will an older config.ini work with this version? I have not touched my live trading config.ini.

Yes, Pranav. It’s not necessary to change config.ini unless you want to take advantage of new features.
